Bruce,
After seeing your info on Mario, i called him, last Wed. He is only 160 miles South of me.
A great guy to talk to and he's been in the business for 50 years. I believe, before moving to Redding, he work at a shop that built Sprint Cars. He will also do off set grinding on rod throws. That's what I was inquiring about.
Are you in Shasta or Siskiyou Co. I lived in Yreka, for 10 years, before moving here.
